The XTA-120V-6 optocoupler module provides six individually isolated 120V AC/DC digital (discrete) inputs to sense on/off levels and drive open-drain outputs. It is intended for use with BusWorks XT Series discrete I/O and other digital input modules to monitor contact closures or mains power supply high/low voltage levels. Each channel senses the presence or absence of high-level voltage to determine the status of proximity switches, limit switches, toggle switches, push buttons, contacts, and other devices. Opto-isolators control an open-drain output to safely interface the status of the monitored signal. These modules are very easy to use. Removable front-facing terminal blocks on the module’s top and bottom greatly simplify field wiring. Rugged construction and high density design combine for a very effective I/O solution. These units are ideal for remote monitoring, distributed control, or SCADA applications. Input Ranges: 0-130Vrms or ±130V DC Output Ranges: Open-drain: 1KΩ pull-up to +5.3V DC, 0-32V DC maximum, 150mA sink Power Requirement: 12 to 32V DC (0.4W)

Performance Specifications


Input Type: Six individually isolated voltage inputs interface voltage levels. Built-in hysteresis provides a sensing threshold for monitoring mains power. Input Signal Voltage Range: 0-130Vrms or ±130V DC Input Signal Threshold: Low-to-High threshold: 90V AC or DC, typical. High-to-Low threshold: 60V AC (55V DC), typical. Input Hysteresis: 30V DC, typical Input Impedance: 46K ohms, typical Input Over-Voltage Protection: Metal Oxide Varistors (MOV) at every channel input. Rated Continuous Voltage: 130Vrms, 130V DC. Rated Maximum Clamping Voltage: 340V DC. Input channels also include capacitive filtering, and series resistance.


Output Type: Six open-drain, mosfet switches with a common source connection at output return. Low-side (sinking) switching between load and return for DC voltage and current-sinking applications only. Output channels are pulled up to +5.3V with 1KΩ resistors. Output “OFF” Voltage Range: 0-32V DC maximum Output “OFF” Leakage Current: 1µA typical, 50µA maximum (mosfet only, 25°C, 32V DC) Output Pull-Ups: 1KΩ pull-ups to 5.3V DC Output Activation: Input                                  Output HIGH > 90V AC/DC      5.3V (OFF) LOW < 60V AC/DC           0V (ON) Output “ON” Current Range: 0 to 150mA DC, continuous, each channel Output Rds On Resistance: 2.5 ohms, maximum (150mA, 85°C) Output Response Time: 45ms, typical (measured from input transition to output) Output Pull-ups: Individual output channels include 1KΩ pull-ups to the internal +5.3V DC rail. If a stronger pull-up (lower resistance) is required, a resistor will have to be wired externally in parallel with the output channel. Note: Do not exceed 150mA of drain current per output channel.
